As shown in Fig. 2 in order to further improve crushing effect, smashing portion is additionally provided between pickup portion 2 and stirring cage 10
3, after pickup portion 2 picks up and enters preliminary crushing to straw, demand enters smashing portion 3 and carries out separating twice.
As shown in Figure 2 and Figure 5, smashing portion 3 includes crushing cutter shaft 31, crush hammer leaf 32 and crushing stationary knife group 33, wherein, powder
The both ends of broken cutter shaft 31 are connected by bearing with the support body right coaming plate 13 of support body left coaming plate 12 respectively, enable crushing cutter shaft 31
Rotated relative to support body 1, multiple being arranged on for the crushing interleaved of hammer leaf 32 are crushed on cutter shaft 31, it is preferable that are crushed hammer leaf 32 and cut with scissors
Connect to be fixed on and crush on cutter shaft 31.
Preferably, the rear side corner that stationary knife group 33 sets coaming plate 11 on support body is crushed, and crushes stationary knife group 33 including more
Individual crushing stationary knife 331, and multiple inner sides for crushing stationary knife 331 and being disposed on support body 1, when crushing the rotation of cutter shaft 31, drive powder
Broken hammer leaf 32 rotates, and when crushing hammer leaf 32 by crushing the region residing for stationary knife group 23, crushes hammer leaf 32 from crushing stationary knife 331
Interval in by, make crushing hammer leaf 32 with crush stationary knife 331 formed compared with Strong shear power.
Preferably, crush hammer leaf 32 from crush stationary knife group 33 by when crush hammer leaf 32 and deeply crush the interval of stationary knife 331
Depth be 1cm-3cm, it is highly preferred that the depth at interval for deeply crushing stationary knife 331 is 2cm.
In the present embodiment, as shown in fig. 6, crushing hammer leaf 32 includes contiguous block 321 and multiple Disintegrating knifes 322, multiple powder
The broken parallel interval of blade 322 is arranged on contiguous block 321, and contiguous block 321, which is hingedly fixed in, to be crushed on cutter shaft 31.
Although most of larger-size straw can be through crushing the cycle rotation quilt at crushing stationary knife group 33 again of hammer leaf 32
Crush again, but in order to avoid the larger straw of portion size falls directly on ground, in certain embodiments, further,
The downside of smashing portion 3 sets broken sieve 4, for preventing longer straw from directly returning field.Specifically, the both ends for crushing sieve 4 are fixed
In support body left coaming plate 12 and support body right coaming plate 13, the straw of longer dimension is fallen on broken sieve 4 and by the crushing of high-speed rotation
Hammer leaf 32 is taken away to be crushed again.
In the present embodiment, specifically, it is broken including the first broken sieve part 41, the first deflector 42 and second to crush sieve 4
Sieve part 43, and the first deflector 42 is located between the first broken broken sieve part 43 of sieve part 41 and second, and the first broken sieve part 41
Between smashing portion 3 and straw entrance 1011, the straw that is flown out from the smashing portion a, part is less than the first broken sieve part 41
The straw of sieve aperture enters stirring cage screen drum 101 through sieve aperture by the straw entrance 1011, and another part is more than the first broken sieve part
After the acceleration of the first deflector 42 after the second broken sieve part 43 screens again, the straw of large-size circulates the straw of 41 sieve apertures
Crushed again to smashing portion 3.Preferably, the first deflector 42 is circular arc.
As shown in Figure 8 and Figure 9, the first broken sieve part 41 in the present embodiment includes multiple longitudinal gratings 44 and multiple transverse directions
Grating 45, multiple longitudinal parallel intervals of grating 44 are set, and preferably, longitudinal grating 44 is arc thin slice, and horizontal grating 45 hangs down
Directly in longitudinal grating 44, and multiple longitudinal gratings 44 are connected, multiple horizontal parallel intervals of grating 45 are set, and laterally sieve
Bar 45 is cylindric, and when crushing the rotation of cutter shaft 31, each Disintegrating knife 321 is between the longitudinal grating 44 of adjacent two
Interval pass through, and go deep into interval, prevent straw overstocks herein from blocking broken sieve 4, it is preferable that Disintegrating knife 321 is deeply indulged
Depth into the interval of grating 44 is 1cm-3cm, it is highly preferred that the depth for going deep into longitudinal grating 44 is 2cm.
Preferably, the spacing between two neighboring longitudinal grating 44 is 3cm；Between the two neighboring horizontal grating 45
Spacing is 2cm.
Five spaced Disintegrating knifes 321 pass through from five intervals of longitudinal grating 44 in the present embodiment, make longer
Straw it is more enough preferably crush.
Further, it is as shown in Figure 8 and Figure 9, more being arranged at intervals longitudinally in each on grating 44 in order to improve crushing effect
Individual detent projection 411, for stopping larger straw, and crushing hammer leaf 32 is coordinated to crush the straw stopped again.
That is straw is after the crushing of smashing portion 3, and larger-size straw can crush again through the first broken sieve part 41, then
After the acceleration of the first deflector 42, crushed again into the second broken sieve part 43, straw is by pickup portion 2, smashing portion 3, first
The crushing that broken sieve part 41 and second crushes sieve part 43 is attained by returning to the field requirement substantially, crushes, carries substantially without circulation again
High crush efficiency.And a small amount of remaining not pulverized stalk enters crush cycle next time with air-flow.
It should be noted that the second broken sieve part 43 is identical with the structure of the first broken sieve part 41, repeating no more.
Further, pick up the efficiency of straw to improve, as shown in Figure 2, it is preferable that pickup portion 2 and smashing portion 3 it
Between the second deflector 5 is set, the both ends of second deflector 5 are separately fixed in support body left coaming plate 12 and support body right coaming plate 13,
And second deflector 5 top and support body on also leave certain intervals between coaming plate 11, make phase between smashing portion 3 and pickup portion 2
It is logical.
Preferably, as shown in Figure 2 and Figure 7, the second deflector 5 is concave curved plate, and cancave cambered surface direction picks up the direction of cutter shaft 21,
When pickup cutter shaft 21 rotates at a high speed, support body coaming plate and the collective effect of the second deflector 5, high-speed air circulation is formed, straw is rolled up
Take and be adsorbed onto pickup portion 2, smashing portion 3 is then entered in the presence of support body coaming plate.
Further, as shown in Figure 2 and Figure 7, it is provided with the downside of the second deflector 5 and hugs careless portion, this hugs careless portion including more
The individual spaced straw hugged careless elastic claw 6, hug that careless elastic claw 6 is flexible, will can be picked up with straw and periphery in furrow
